The structure of strychnofluorine, an indole alkaloid isolated in 1980 from the root bark of Strychnos gossweileri, has been revised. Strychnofluorine proved to be identical with 18-hydroxynorfluorocurarine that has been isolated as a minor (contaminated) alkaloid from Strychnos ngouniensis in 1983. [less ▲]

The structure of strychnochromine, an unusual alkaloid isolated from a new batch of the root bark of Strychnos gossweileri has been revised . To confirm the indoline structure ( proposed in 1988) and to establish the stereochemistry of the compound extensive 2D-NMR experiments were carried out. The COSY experiments mostly confirmed the previous observations but the COLOC maps did not fit the first proposed structure!The problem was solved by single-crystal X-ray analysis of the p-bromobenzoyl ester of strychnochromine. The new structure, with its tetrahydroquinoline ring, is very unusual in Strychnos species but the formation of quinolines from indole alkaloids has already mentioned in some other plants ( Cinchona, Alstonia, Hunteria..).

In previous papers, we related the isolation and identification of several indole alkaloids from the root-bark of Strychnos gossweileri: alstonine, a well known anhydronium base, dolichantoside a new indol-glucoalkaloid and diploceline, a new quaternary alkaloid. From a second batch of the same species, we isolated, besides the previously isolated compounds, three new alkaloids. The structure elucidation and the stereochemistry of these alkaloids ( isodolichantoside, strychnofluorine and 16-epi-diploceline) are now discussed. [less ▲]

Strychnos icaja roots are used in Central Africa for the preparation of arrow and ordeal poisons. Amongst the very numerous bases present in these roots, we have isolated and identified six alkaloids. Apart from strychnine, we have obtained three alkaloids previously detected in the leaves:icajine, 19,20-alpha-epoxynovacine and 19,20-alpha-epoxy-15-hydroxynovacine. Moreover we have extracted dimeric alkaloids: symmetrical (bisnordihydrotoxiferine) as well as a new unsymmetrical one (sungucine). Finally it has been shown that the plant contained also various quaternary alkaloids and particularly Nb-methylstrychninium base which has been found for the first time. Phytochemical and pharmacological experiments are still under study. [less ▲]

Fourteen bis-indole alkaloids have been isolated from Strychnos usambarensis leaves. Nine are described here for the frst time: 18,19-dihydro-usambarine; usambaridines and their dihydroderivatives; strychnobaridine; strychnopentamine and isomers. The elucidation of structure and the stereochemistry of these new compounds are also discussed. They possess the "usambarane" skeleton; moreover many are phenolic and amongst them, strychnopentamine and isomers are curiuos alkaloids with five nitrogen atoms: a methylpyrrolidine group is joined to the indole ring of the corynane part of the molecule.
